To assess the potential value of the AMAK treatment and
filtration process, we compared it with other methods for manure
treatment (Table 6). Other methods included the BIOSORTMManure
biofiltration process (Buelna et al., 2008), the BIOREK
membrane method (Du Preez et al., 2005), the SELCO-Ecopurin
separation method (Martinez-Almela and Barrera, 2005), and the
PIGMAN separation concept (Karakashev et al., 2008).
